<h2>Description</h2>
<p class="Body">A sparse point gradient interpolator using a inverse <em>bilinear</em> interpolation<br>
Based on four (and only four) vertices, with each vertex specified with a certain color, an inverse bilinear interpolation of color is calculated. 
Outside this continue the colours continue as before, but discontinuities may occur.
